Different Selection based on figures [message #221041]

I have a compartment figure (like the circuits in the logic example).
Unlike the circuits, my figure has a title bar. I would like to change
the selection tool based on where in the figure the mouse down is
pressed. If the user selects inside the compartment then I would like
to use a Marguee selection. If they select the title, then i would like
to use a single selection tool.

I know I need to override the getDragTracker() method in my edit part,
but since my title and compartment areas are just figures within my
compartment figure (and not edit parts), I am not able to determine
where the selection occurred. i really don't want to create separate
edit parts for these two parts of my compartment edit part.

any ideas?

cheers,
ian

You should be able to call containsPoint() in each of the figure for the
editpart and determine which figure has the mouse "focus"
